Radioactive waste package analysis system and associated analysis method

摘要

The invention relates to a system (2) for analyzing radioactive waste packages (4) comprising a source (6) of neutrons, the analysis system (2) comprising: - at least one detection device (10) configured for detecting fast neutrons and / or thermal neutrons, and for delivering a detection signal comprising pulses each representative of the detection of a corresponding neutron; - a computer (12) configured to: • identify, in each detection signal, the pulses corresponding to thermal and / or fast neutrons; • calculate, for each detection device (10), a first number of coincidences, depending on the number of real coincidences of fast fission neutrons detected, and / or a second number of coincidences, depending on the number of real coincidences of thermal neutrons of fission detected; • determining a position of the source (6) from the first number of detections and the second number of calculated detections.
